intermediate commit - still trying to fix the states of the OSC-button in the widget

tracking the wrong display of the oscBut in CVWidgetMS - it looks like I forgot that oscBut.states[0] is an array itself… still wondering why clicking the button and opening the editor changes the colors back to black (text), white (background) - investigating...

solved: oscBut resp. midiBut should keep their colors if any connections are present and mouse hovers over them.
